What cam would you run?

I think I should say that this isn't a full blown race car. I do drive it on the street more than the strip.

Do I need to ditch the 1.6 rockers? I'd rather not if I don't have to... How much lift can I get away with before I need to pull the heads and have them reworked?

I've been mulling over having the converter restalled at some point, I guess this would be the push to get it done.
